[strike]What gun are you using? Not all guns can shoot multiple times, it says the ammount of rounds on the item's description window. You can open it by double clicking the item, or if it's already equiped, by clicking that black and white button by the right side of the equiped item that looks like a sideways eye.[/strike]

EDIT: I have to apologize but I misread what you wrote.
